A 4.2 mm self-drilling screw that cuts a clean hole through a 2 mm steel bracket will spin in place on a 0.8 mm cladding panel, and the same screw that holds a dry indoor ceiling together can rust to the surface within a season on a coastal roof. Neither failure is a manufacturi...

READ MOREAnhui Linghong Hardware Technology Co., Ltd. is a China-based manufacturer and supplier of Wafer Head Self-Tapping Screws, engineered for thin-plate fastening in sheet metal, steel framing, and light-gauge assembly. Our screws combine a low-profile, wide head with self-tapping threads to deliver secure joints without pre-drilling or additional washers.
With over 20 years in the fastener industry and a 12,600 m² factory in Anhui, we produce more than 500 tons of screws monthly. Our wafer head range is available in carbon steel and stainless steel, with various coatings and drive options to match your application and environmental requirements.
We supply two primary types of wafer head self-tapping screws:
Typical applications include:
The wide, thin head acts as an integrated washer, distributing clamping force to prevent deformation of soft materials like galvanized steel, gypsum board, and aluminum.
We manufacture wafer head screws from high-quality carbon steel (e.g., C1022A) or stainless steel (e.g., 304, 410) to match your corrosion and strength needs. Standard finishes include:
Drive recesses are typically Phillips (PH2) or Torx (T15, T20) to ensure stable bit engagement and reduce cam-out during high-speed installation.
Our wafer head screws are produced to meet common industry dimensions and performance expectations. Key parameters include:
| Parameter | Typical Range | Notes |
|---|---|---|
| Diameter | #6 to #14 (3.5 mm – 6.3 mm) | Custom sizes on request |
| Length | 12 mm to 100 mm | Increments of 1 mm or 1/8 inch |
| Head diameter | Wide, thin profile (approx. 2x shank) | Provides washer effect |
| Thread type | Self-tapping (cutting) or self-drilling | Drill point for steel |
| Hardness | Core hardness typically HV 450–560 | Surface hardness for case-hardened |
We control hardness and case depth using Rockwell hardness testers and metallographic analysis, ensuring consistent thread forming and resistance to stripping.
We offer flexible configuration to match your assembly line and end-use requirements:
Our engineering team reviews your drawings or samples to produce a screw that meets your dimensional and performance targets.
We operate under ISO 9001, ISO 14001, and ISO 45001 certified systems. Every batch undergoes first-piece inspection, in-process patrol checks, and final random sampling before shipment. Our in-house lab is equipped with:
We also perform dimensional checks using optical comparators and thread gauges to ensure compliance with your specifications.
Wafer head self-tapping screws are designed for power driving. For best results:
No special maintenance is required after installation; the coating protects against corrosion in indoor or mild outdoor environments.

With this information, we can recommend the optimal screw design and provide a competitive quote.
The wafer head has a wider, thinner profile compared to a pan head. This provides a larger bearing surface that acts like a washer, reducing the risk of crushing soft materials. It also sits lower, offering a cleaner finish.
Yes, we offer both standard self-tapping points and self-drilling points. The self-drilling version eliminates pre-drilling and is ideal for fastening into light-gauge steel up to about 1.2 mm thick.
We provide white zinc, yellow zinc, blue rust-proof coating, black phosphate, and other custom finishes. For outdoor or high-humidity environments, stainless steel is also available.
Absolutely. We can produce custom diameters, lengths, and head dimensions to your specifications. Packaging can be bulk, retail-ready, or collated for automated screw feeders.
Lead time depends on quantity and customization. For standard items, we typically ship within 2–3 weeks after order confirmation. Custom products may require additional time for tooling and sampling.
Our portfolio also includes Products, Wood Screw, Carbon Steel Wood Screws for applications with different operating ranges, interfaces or integration requirements.
